 Plotting routines used to visualise data. The following types of
 graphs can be employed:

  (i)   Plot
  (ii)  Image
  (iii) Pseudo-Colour
  (iv)  Waterfall (1 and 2)
  (v)   TFSAPL
  (vi)  TFSAPLL
  
 EXPLANATION OF VARIOUS PLOTTING ROUTINES

  (i) Plot
      
      Used for one dimensional plots of signals, IF estimation,
      wavelet coefficients, frequency spectra etc.

  (ii) Image

      Used to plot two dimensional matrices such as time-frequency
      distributions and scalograms. Displays the matrix as an image.

  (iii) Pseudo-Colour

      Pseudo-colour plots a colour grid for each element of the input
      matrix. Also used to plot two dimensional matrices such as
      time-frequency distributions and scalograms.

  (iv) Waterfall 1 and 2

      Again also used to plot two dimensional matrices such as
      time-frequency distributions and scalograms. This uses a
      waterfall style plot of the matrix, using different viewing
      angles which distinguish Waterfall 1 and Waterfall 2.

  (v) TFSAL

       Used to display the time-frequency distribution matrix over
       the time-frequency plane. Subplots of the time domain signal
       and the power spectrum are provided along the axises of the
       time-frequency plot.

  (vi) TFSAPLL

       Equivalent to TFSAPL except the log of the time-frequency
       distribution is plotted.</pre></div>
